Description
i7 This inv~n~ion relates to the bon;.nq of meat and in particular this invention relates to a device for remov;nq the bone from a pi.ece of meat such as a rib of beef, leg of ham or legs of fowl. of the like.
In pr;or devices for removinq a bone from meat considerable difficu]ty has been experienced in attempting to avoid crushing of the bone. In addit;on, diff;culty has been experienced attempting to severe the meat ti.ssue membranes and sinews would serve to attach the meat to the hone.
The present. apparatus overcomes the diff;culties associated wi.th the severinq of the si.news by providinq at least one restinq member which serv~s to prevent displacement of sinews laterally beyond the cutting edge during the closing o~ the deboning dies.
The difficulties which have been experienced in attempting to reduce bone breal~age are qreatly reduced by the provision of at least two compression members which are independently moveahle and a bridginq member which extends between the compression members and serves to distr;bute the boning load while permitting the relative movment between the compression members.
According to one aspect of the present invention is provided a boning device for removing meat from a meat bearing bone such as a pork shoulder, ribs, leqs of Fowl or the like comprising, a pair of boning dies mounted for movement toward and away from one another between an open and a closed position, a resil.iently yieldable insert mounted in each die, a bone support face fo-.~med on each resilientlY yieldable insert, said bone support faces being disposed opposite one another and adapted to engage a meat ~k ~.
3~7 D-3h38-1.5~-GF-Specs bearinq bone located there between when said dies are moved toward one another, meat severinq means located on one of said dies for severing the meat when sai.d dies are in said closed position, said meat severinq means extending about the perimeter of said meat supporti.ng faces, at least two compression members mounted on one oF
said die.s i.n a spaced relationsh;.p with respect to its resiliently yieldable insert, said compression members being laterally spaced from one another, ~sa;d compression members being operable to move independently with respect to one another from a retracted positon to an extended posi.tion to press the support faces toward one another to apply a boning load to a meat bearing bone in use, bridging means bridging said compression members, said bridqing means being located between said compression members and their associated resiliently yieldable insert, said bridging means being movable relative to said compression members, supports to distribute the boning load across said resiliently yieldable insert while permitting relative movement between the compression members.
Accordinq to another aspect of the present inventi.on there is provided a boning device for removing meat from a meat bearing bone such as a pork shoulder, ribs, leqs of fowl or the like comprising, a pair of boning dies mounted for movement toward and away from one another between an open and a closed position, a resiliently yieldable insert mounted in each die, a bone support face formed on each resiliently yieldable insert, said bone support faces being disposed opposite one another and adapted to engage a meat bearing bone locate~ therebetween when said dies are moved toward one another, meat severing means located on one of said dies ~,~ ?;, lZ~ 7 D-3638-152-GF-Specs -Eor sever;.nq the meat when sa;d dies are in sai.d clo.sed po~sition, said meat severing means extend;nq ahout. the perimeter of sa;.d bone supporting -faces, an arresting member mounted on one of said dies inwardly of said perimeter and projecting outwardly from its hone support face tw~ard the other die so as to close against the bone support face of the other dies before said dies are fully closed to clamp and retain an sinew which is located therebetween prior the final closinq of the dies to sever the meat in use.
According to yet another aspect of the present invention there is provided a method for removing meat from a bone to which it is naturally secured by attachinq membrane such as sinew or the like comprisi.nq the steps of, subjec-t;.ng a meat bearing bone to an initial compre~sion by locatinq it between two opposed dies and partially closing the dies to contain the bone and to displace a substantial portion of the meat laterally ~rom the bone through a narrow gap formed between the partially closed dies, subjecting the meat bearinq bnne to a secondary compression at a pressure greater than that of the initial compression, but which is less than that required to break the bone, while the di.es are retained in their partially closed position, to expel substantially all of the remaining meat from the bone throught said gap, and closing said dies to sever the meat and/or attaching membrane which is located therebetween without breakinq the bone.
The invention will be described more fully with reference to an embodiment.

Fig. 1 a plan v;ew of a cutt;ng element embodyinq the invention prov;.ded with arresting member.s, Fig. 2 a sectional v;.ew taken on the line II-II in fig. 1, Fig. 3 a sectional view taken on the line III-ITI in fig. ]., Fiq. 4 a vertical sect;ona] view of part o~ the device with respect to the cu~ting and counter elements, the sectional view of the cutting element being taken on the line V-V in fiq. 5 and VI-VI
in fig. 6~
Fig. 5 a plan view of the cuttinq element, Fiq. 6 a bottom view of the counter element, Fig. 7 a sect;onal view taken on the line VII-VII in fig. 5.
Referri.ng to the figures reference numeral 1 designates the upper counter element having a wall. part 3 standing on a carrying plate 2. The shape of the wall part 3 matches the contour line around the bone B to be cut out (see figs. I and 2).
Below the counter element l is arranged a cutting element fastened in a similar manner to a supporting plate (not shown) and also constructed in the form of a wall part 4 corresponding with the wall part 3. The wall parts 3 and 4 constitute the cutting or punching matrices proper. The top side of the wall part 4 is bevelled and terminates in a cutting edge 5, which co-operates with the flat underside of the wall part 3 (see fig. 2).
A cavity formed by the wall parts 3 and 4 is filled with a flexible mass 6, which may be formed by various layers of a material having relatively different elasticities. Furthermore, the cutting matrix is constructed with a stamp 7 carried by a plunger 8 in order ,, ~ "
~2i~7 D-3638-152-GF-Specs to cause the ~lexihle layers ~ to yield during punching. The plunqer 8 ~orms part of the hydraulic drivinq circult by which also the matrices 3 and 4 are moved towards and away ~rom one another.
Inside the standing walls 3 and ~ of the matrices are arranged arresting elements 9 extending as far as beyond the cutting edge 5 and and underside of the matrix 3 respect;vely in the direction towards the opposite matrix element. The arresting elements 9 have a relatively small size and brinq about an arrestinq effect at those places where sinews and/or membranes of the bone B
might be urged laterally beyond the cutting edqe 5 during the cutting operation. The arresting members may have any shape~ The arresting members 9' have the shape of plates curved in accordance with the contour line of the wall part 3. On the contrary, the arresting element 9'' has a lense-shaped cross-section and has a ~lat side 10 ~acing the bone. The arresting element 9''' has a trapezoidal cross-section, the top being directed towards the bone.
Finally the arresting element 9'''' has the shape of a stamp having a vaulted top ~ace rising in outward direction. On the side facing the bone the stamp has crescent-shaped recesses 11 in which fits the pro~ectinq part of one part of the bone s.
It should be noted that the matrix with the arresting members arranged therein is specularly symmetrical with respect to the sectional line III-III (see fig. 1) in order to permit o~
working the le~t-hand and right-hand shoulder pieces with the same matrix.
.J~"~ .
,7 D-3638 152-GF-Specs Each arrestinq member 9 is supported on the bottom of the cav;ty in the matrix of the coun~er element 3 or in a recess in the wall part 4 oE the cuttin~ element (see Eig. 3). In this way a firm support is ensured for the arrestin~ members.
.. i .
Moreover, each arresting membe~ is releasably fastened by means of a screw nipple 12 in the cavity so that the matrix can be simply adapted to differently shaped bone pieces by arranging matching arresting members therein.
From the figures it is apparent that the arresting members 9 are disposed so that they exactly slide along the inner wall of the opposite matrix wall when the cutting and counter elements are driven. In this way an acc~-rate seal is ensured because the arresting member presses by 10 its end edge against the fle~ible mass.
The invention is not limited to the above-des-cri~ed embodiment. Within the scope of the invention an em-bodiment can be conceived in which the arresting elements are movably arranged in the matrix, when the flexible filling of 15 the matrices is dispensed with.
Referring now to the figures 4-7, reference numeral 31 designates the cutting element having an upwardly directed cutting edge 32. The cutting edge co-operates with the counter-element 33, the elements being pressed to one 20 another as shown in fig. 4 by means of a hydraulic ram (not shown~.
The elements are supported by carriers 34 and 35 respectively, the carriers 34, for example, being fastened to a slide 36 reciprocated by the ram in the direction of the 25 arrow P1, whereas the carrier 35 is rigidly secured in the frame 37 of the device.
The cavity 38 of the cutting element 31 acco-modates a plurality of supporting members 39 movable in the direction of the arrow P1 and having the shape of a stamp.
30 Each stamp 39 is carried by a pin 40 connected with a bender 41, which is operative in a cylindrical space 42 in the car-rier 34.
The size and the shape of the stamps 39 depend on the place accopied thereby in the cavity 38 of the cutting 35 element.
At least two stamps are provided each with a bridge piece 43, the bridge piece being covered by a layer of elastic material 44. The layer 44 may have cavities 45 for C~
. ,~
receivin~ thick parts of the piece of bone, ~or example, joints between the hones.
The counter element is also provided with recesses 46. The recesses 45, 46 of the cut~ing and counter elements respectively need not be directly located one above the other, they may be relatively off-set in the horizontal plane. This depends on the shape of the thickened piece of bone and it contributes to an improved positioning or clamping of the piece of bone during pressing, The bridge piece 43 may be locally provided along the circumference with raised parts projecting towards the counter element and extending above the elastic layer 44, said parts 47 being indicated in the drawing at the ends oE
the bridge pieces.
There may furthermore be provided filling pieces 48, which may have any shape and which are preferably removable from the cavity 38 so that they can be replaced by other pieces in accordance with other kinds of meat to be treated.
The filling piece ~8 may, as a whole, be firm-ly supported in the element. As shown in fig. 7 the filling piece 48 may lie on the one hand on a projecting face of the element and on the other hand on the top face of the bridge piece 43. As a further alternative the support may be provi-25 ded by the yielding members 39, 4~.
The cavity in the counter element may also be provided with filling pieces 49 having a bone and meat gui-ding function respectively.
The device described above operates as 30 follows:
After the cutting elements 31 on the slide 36 has been lowered, a space is formed between the t~o elements so that the piece of meat to be processed can be deposited on the cutting element 31. The user has to arrange the piece of 35 bone above the cavity 8 of the cutting element, after which he act~ates the device so that the cutting element 31 is mo-ved upwards in the direction of the arrow P1. The piece of the bon~ itself finds the cavities 45 and 46 respectively and if the piece of bone comprises two pivoting bones, it assumes the positions indicated by the lines V-V and VI-VI respecti-vely.
During the further upward movement, before the cutting edge reaches the counter element, the rams 42 are energized by supplying a fluid so that the stamps 39 are mo-ved upwards and press the piece of bone by high pressure be-tween the elastic layers 44. The residual meat is moved be-yond the cutting edge 32, after which the meat is severed.
Sinew and connective tissue are retained inside the cutting edge 32 by the extensions 47 of the bridge piece 43 and the filling pieces 48, 49 respectively.
Bone fracture is now avoided since the non-uniform, vertical movements of the stamps 39 are averaged because the piece of bone is lying on a bridge piece 43. It will be obvious that the bridge pieces 43 can freely tilt in the cavity 38 so that the supporting face on the top face of the bridge pieces 43 may be sharply bent.
The filling piece 48 will also perform a til-ting movement in clockwise direction (fig. 7), which movement ensures correct centering of the bone. During pressing after the establishment of the contact of the cutting element with the counter element meat residues will assembly in the pres-sing cavity and be conducted away through passages 50.
The invention is not limited to the embodi-ments described above.
